The journey to CMMC Level 3 represents the highest level of cybersecurity maturity under the CMMC framework. Unlike Levels 1 and 2, which focus on FCI and CUI, respectively, Level 3 targets Advanced Persistent Threats (APTs). That means more extensive security, defined in NIST Special Publication 800-172.
For organizations that support critical programs or handle high-value assets for the Department of Defense, achieving Level 3 is imperative. But what does it take to implement the enhanced controls from NIST SP 800-172, and how do they fit into the broader CMMC ecosystem? This article explores that challenge and provides a practical roadmap for organizations preparing to meet it.
